SIEGIFICATION forming part of Letters Patent No. 786,723, dated April 4,1905.

Application filed June 11,1904. Serial No. 2l2,063.

To a whom) it may concern:

Be it known that I, PETER BROADBOOKS, a citizen of the United States,residing at Batavia, county of Genesee, andState of New York, haveinvented a certain new and useful Improvement in Nippers orCutting-Pliers, of which the following is a specification.

My invention relates to a new and useful improvement in nippers orcutting-pliers; and niy object is to so construct a tool of thisdescription as to gain rigidity and overcome the side strain the jawsare subjected to in cutting large wire on 'the outer edge thereof.

Another object of my invention is to provide cutting-jaws which aresolid and integral 7 with their shanks and hinging said jaws togetherupon the same pivot as the levers.

Another object is to so construct the cuttingaws that while they areadjustably and removably attached tothe levers are at the same timerigidly held in a receptacle formed in the head of each lever andbetween the flanges of the inner lever.

Another object of my invention is to construct the receptacle in whichthe jaws are held so that the outer walls of said receptacles will beardirectly against the shank of the cutting-jaws, and thus insure greatrigidity, and by hinging said aws to the same fulcrum-pivot as thelevers said jaws are kept from twisting. I

With these ends in viewthis invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claim.

in order that those skilled in the art to which this inventionappertains may understand how to 'make and use the same, theconstruction and operation will now be described in detail, referring tothe accompanying drawings, forming a part of this specification, inwhich- Figure 1 is a side view of a pair of nippers made in accordancewith my improvement; Fig. 2, a longitudinal section through the same;Fig. 3, a section taken on the line 3 3 .of Fig. 1;' Fig. 4:, aperspective view of one of thecutting-jaws and shank.

A and B represent two levers, each lever belng cut away at one end, soas to form the side flanges A and B, respectively. These levers are cutaway at this end, so that one may pass through the other and be hingedtogether by the'pivot C. I

D represents the cutting-jaws, each of which has a shank D formed withit. One of these jaws is adapted to fit between the flanges of eachlever, a screw or bolt passing through the flanges of the lever andthrough the shanks of the jaws.

ing-rings D", adapted to surround the pivot C between the flanges A ofthe inner lever A. .The solid portions formed at A and B in the head ofthe flanges of the levers A and B, respectively, beyond the cut-awayportions are adapted to contact the shanks D of the jaws, so that thestrain in cutting; is not taken by the bolts or screws E; but thepressure is di ,rectly applied from the levers by the solid portions Aand B coming in contact with the jaws. It will thus be seen that thecut-away portions at the head of the flanges of each oi? the leversprovide a receptacle for the jaws, and these jaws may be removed at anytime by removing the bolts or screws E and pivot C, and if the cuttingedges of the jaws arev Worn away in sharpening or repairing they can beadjusted by enlarging the holes through which the bolts or screws passand putting a liner between the solid portions A and B and the shanks ofthe jaws. This is an important point in pliers of this character, as thecuttingedges of the jaws may be repaired and exactly or accuratelyfitted independent of the levers and used with greater economy.

F is a screw adapted to be threaded through one of the levers and bearagainst the other lever for limiting the movement of the jaws toward oneanother. 7

It will thus be seen that by this construction of cutting-pliers I haveprovided a tool which accomplishes all the objects before stated and atthe same time consists of very few parts, thus making the tool cheap tomanufacture, durable, and extremely eificient in action.

Of course 1 do not wish to be limited to the exact construction hereinshown, as slight The inner ends of the shanks of the jaws are providedwith bearmodifications could he made without departing from the spiritof my invention.

Having thus fully described my invention, what I claim as new and usefulis- In a cutting-pliers, two levers, the flanges of one lever adapted topass between the flanges of the other lever and be hinged together atthis point, receptacles formed at the head of the flanges of each lever,euttingjaws' provided with shanks, said shanks adapted to lit within thereceptacles formed in the end of each of the levers, said shanks beingled together, the pivot which pivots the lovers together adapted to passthrough both shanks, bolts or screws passing through the levers and l ir through the shanks above the pivotal point, the outer walls of thereceptacles adapted to bear against the shanks oi the cutting-jaws sothat the power from the levers is communicated to the jaws through theseouter walls, thus removing all strain from the bolts or screws whichpass through the lovers and shanks.

in testimony whereof l have hereunto affixed my signutin'e in thepresence of two silhscrihing witnesses.
